Koyomi no Wa — 72 Seasons

A Japanese year is more than four seasons.
It turns through 24 solar terms — and within the "72 micro-seasons" (shichijuni-ko), the season shifts every five days. "Self-heal withers," "Cherry blossoms begin to open" — the delicate faces of the seasons that people of old once watched. Koyomi no Wa quietly tells you which one is unfolding today.

■ What season is today?
- Today's micro-season, with clear, gentle notes anyone can read
- A related ukiyo-e (public-domain masterpiece) and a classic haiku
- Rokuyo, the lunar date, the sexagenary day, holidays, seasonal markers (Setsubun, Day of the Ox…), and lucky days
- The moon's phase, and the foods and flowers in season now
- "Sakuya's Column for Today" — a seasonal essay for all 366 days of the year

■ Beautiful, and quiet.
- "The Wheel" — see the whole year as a circle of 24 terms
- A washi-paper background that shifts with the seasons
- The dignified type of Shippori Mincho
- Save and share today as a lovely card

■ Gentle by design
- Fully offline. No networking at all
- No ads, no in-app purchases
- A soft daily notification (choose: today's season / start of a term / seasonal markers / lucky days)
- Home-screen widget
- Japanese and English
